Title: Microfilm projecting lens system
Inventor: UEDA TOSHIHIKO
IPC: G02B9/60
Filed: 1987-11-06
Abstract: PURPOSE:To miniaturize an image rotating prism and to obtain a projecting lens system which is well corrected in various aberrations and has good performance by disposing an incident pupil to the end part of the projecting lens system. CONSTITUTION:The incident pupil position to which luminous fluxes are most converted is disposed to the end face on the magnification side of the projecting lens system and the image rotating prism is disposed in the position extremely near the end face. For example, a 3rd lens group III of a biconvex lens is so formed as to correct the distortion aberration in a negative direction generated on the r9 face of a 2nd lens group II at the r10 face and this final lens is composed of the positive lens having a relatively strong power, by which the pupil position on the reduction side is brought to the position further from the magnification side as compared to the focal length. A stop is disposed nearer the magnification side than the r5 face of the 1st lens group I to decrease the spread of the off axial luminous fluxes on the 1st face r1, thereby miniaturizing the image rotating prism disposed on the magnification side which is a screen side. The deterioration of the projected image is thereby minimized and the image rotating prism and projecting optical system are miniaturized over the entire part.

Abstract: PURPOSE:To stably recognize the magnetic pattern of a bill by forming the tip part of a magnetic sensor in a curved surface shape in the bill recognizing device equipped with a decision circuit which decides that a bill is a read one of a forgery and also on its money classification. CONSTITUTION:Plural magnetic sensors 12 whose tip parts are projected into a conveyance path 14 behind a bill recognition part are provided above the conveyance path 14. Each magnetic sensor 12 comes into contact with a bill 1 in the conveyance path 14, reads out the magnetic pattern given to the bill 1 and converts it into an electric signal, and sends the signal to the decision circuit 13. The decision circuit 13 decides whether or not the bill 1 is genuine or false and its money classification with the signal sent from the magnetic sensor 12. The tip part of the magnetic sensor 12 is formed in a semispherical shape. Thus, the tip part of the magnetic sensor 12 is formed in the semispherical shape, so when the bill 1 and magnetic sensor 12 come into contact with each other, their relative positions are stable and the state of contact with even a bill which is naturally curled becomes stable. Therefore, the magnetic pattern of the bill 1 can stably be recognized.

Title: Pressure sensitizer
Inventor: IIDA HIDEO
IPC: H01H13/52
Filed: 1987-11-11
Abstract: PURPOSE:To convert a pressure variation into an electric signal by holding a high molecular electric conductor on an electrode, under pressure, by pressure- contact force of a pressure spring, while forming a specified resistance circuit in a gap between a pair of electrodes, and making force from the outside act on the pressure spring. CONSTITUTION:In the state that pressure F from the outside will not acts on a tip 33 of an actuator 3, a high molecular electric conductor 4 tightly attached to the actuator 3 forms resistance circuit in a gap between electrodes 21a, 21b by dint of pressure-contact force of a pressure spring 5. At this time, the conductor 4 is being displaced by receiving compressive deformation due to the pressure-contact force of the pressure spring 5. If the pressure F from the outside is made to act on the tip 33 of the actuator 3, displacement of the actuator 3 also increases with the augmentation of the force F, whereby the conductor 4 is separated from an electrode substrate 2, and a gap between these electrodes 21a, 21b comes to an open circuit. With mechanical operation aforesaid, the gap between these electrodes 21a, 21b is increased to infinity from an initial resistance value, and thereby a pressure sensitizer works as a pressure sensor.
